I must be a pretty average, typical Disney consumer as every time there is a poll, be it 'how long are your trips', or 'how old were you when you purchased DVC', or 'how many DVC points do you own', or you name it, I am always in the category with the largest percentage of responses.
Our trips are typically 7 to 9 days. Two a year, unless I happen to have a business trip - in which case i might ahve a 5 to 7 day trip.
